Be it known that 1,.(WALTER H. PERKINS,

(assignor to the WATERBURY MANUFACTUR- Water-Bottle Stoppers; and I dohereby declare the following, when taken in connection with theaccompanying drawings and the letters of reference marked thereon, to bea f ull, clear, and exact description of the same, and which saiddrawings constitute part of this specification, and represent, in-Figure 1, a view inside elevation o'f-a waterbottle stopper constructedin accordance with my invention; Fig; 2, a view thereof .in verticalsection; Fig. 3, a detached view, inside elevation, of one form whichthe disk may assume; Figs. 4,5, and 6, corresponding views of modifiedforms which the disk may assume. My invention relates to an improvementin water-bottle stoppers, the object being to produce at a low cost formanufacture a sim ple, compact, convenient, and effective deviceconstructed with particular reference to ease In carrying out myinvention as herein shown I employ a struck-up sheet-metalcap having aflat top 2, a knurled edge 3, and an inwardly-turned flange 4, whichissecured to an outwardly-turned flange 5, formed at the upper end ofthe cylindrical sheet-metal body 6 of the stopper, the said body havingthreads rolled into it. The flanges 4 and 5 are secured together bysoldering or otherwise, or the cap and body may be formed of a singlepiece of sheet metal. The lower end of the body 6 is turned inwardly toform an annular flange 7, which is entered into an annular groove 8,formed in the edge of the rubber disk 9, which practically correspondsin diameter to the diameter of thesaid body. When the rubber disk 9 hasits annular groove 8 entered by the annular flange 7, the disk maybesaid to be WALTER H. PERKINS, or WATERBURY, CONNECTICUT, ASSIGNOR TO THEpartly within and partly without the body 6.

.It is very firmly secured in place and has a wide-bearing against theouter face of the flange to resist pressure tending to force it into thebody of the stopper.

fled forms of the disk; but all of them are alike in having an annulargroove to receive an annular flange formed at the lower end of the body,though the portions of the disk separated by the groove, are widelydifierentiated in size, whereas the portions of the disk -9 separated bythe groove 8 practically correspond to each other in diameter.

In view of the'modifications suggested. and

have it understood that'I do not limit myself to the exact constructiondescribed, but hold myself at liberty to make such alterations as fallwithin the scope and spirit of my invention. v

Having fullydescribed my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a water-bottle stopper, the combi naw tion with a threadedsheet-metal body formed at its upper end with an outwardly-turnedannular flange, and at itslower end with an inwardly-turnedannularflange, of a hollow sheet-metal cap larger in diameter than thediameter of the said body,'-formed with a knurled edge and formed atitslower, end with an inwardly-turned annularflange which is secured tothe. said outwardly-turned annular flange at the upper end of the'saidbody I which enters the said hollow cap. for the fastoning of the twosaid flanges together, and

end of the said body and formed in its edge the edge of theinwardly-turnedannular flange located at the lower end of the said withan annular groove for the reception of 9 adisk adapted to partiallyenter into the lower I r entered into the lower end of the said body Intestimony whereof I have signed this and formed in its edge with anannular groove specification in the presence of two subscribfor thereception of the said flange by which it is retained in place, and a capapplied to ing witnesses.
